Claims

[Claims for Utility Model Registration] (1) The axial center of the handgrip section and the axial center of the shaft section that connects the handgrip section and the tip section containing the transducer have an inclination, and the two An ultrasonic probe characterized in that the intersection point formed by the axes is located within the hand grip portion, and the angle formed by the two axes widens toward the tip end. (2) Claim 1, wherein the axial center of the tip section containing the transducer is located between the axial center of the shaft section and the axial center of the hand grip section, and is configured to move parallel to the axial center of the shaft section. Ultrasonic probe as described. (3) The ultrasonic probe according to claim 1 or 2, wherein the tip portion housing the transducer has a pair of engaging recesses on the shaft portion side. (4) The ultrasonic probe according to any one of claims 1 to 3, wherein the hand grip portion has a protrusion on its outer circumferential surface that displays an ultrasonic beam scanning plane and coincides with the inside of the scanning plane. (5) The ultrasonic probe according to any one of claims 1 to 4, wherein the hand grip portion has a stepped portion at the distal end thereof, the diameter being larger on the distal end side. (6) A hand grip of the ultrasonic probe and a claw member that has a needle guide tube through which the puncture needle is inserted, and that engages the engagement recess of the ultrasonic probe according to any one of claims 2 to 5 at the distal end and the base. A puncturing attachment for an ultrasound probe, characterized in that it is provided with a holding frame that holds the base of the ultrasound probe. (7) The claw member engages with the engagement recess of the ultrasonic probe subsequent to the engagement portion where the claw member engages with the outer peripheral portion of the shaft portion of the ultrasonic probe according to any one of claims 1 to 5. 7. The puncture attachment for an ultrasound probe according to claim 6, wherein the puncture attachment is bent substantially parallel to the axis of the needle guide tube. (8) The puncturing attachment for an ultrasonic probe according to claim 6 or 7, wherein the holding frame has a groove on its inner surface that engages with the protrusion according to claim 4. (9) The ultrasonic probe puncture attachment according to any one of claims 6 to 8, wherein the width of both open portions of the holding frame is wider than the maximum diameter of the cable. (10) the holding frame has a pair of nuts at the open end;
